Member Data Documentation

template<class ScalarType, class MV>
int Belos::GmresIterationState< ScalarType, MV >::curDim

The current dimension of the reduction.

This should always be equal to GmresIteration::getCurSubspaceDim()

Definition at line 55 of file BelosGmresIteration.hpp.

template<class ScalarType, class MV>
Teuchos::RCP<const MV> Belos::GmresIterationState< ScalarType, MV >::V

The current Krylov basis.

Definition at line 58 of file BelosGmresIteration.hpp.

template<class ScalarType, class MV>
Teuchos::RCP<const MV> Belos::GmresIterationState< ScalarType, MV >::Z

The current preconditioned Krylov basis (only used in flexible GMRES).

Definition at line 61 of file BelosGmresIteration.hpp.

template<class ScalarType, class MV>
Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > Belos::GmresIterationState< ScalarType, MV >::H

The current Hessenberg matrix.

The curDim by curDim leading submatrix of H is the projection of problem->getOperator() by the first curDim vectors in V.

Definition at line 69 of file BelosGmresIteration.hpp.

template<class ScalarType, class MV>
Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > Belos::GmresIterationState< ScalarType, MV >::R

The current upper-triangular matrix from the QR reduction of H.

Definition at line 72 of file BelosGmresIteration.hpp.

template<class ScalarType, class MV>
Teuchos::RCP<const Teuchos::SerialDenseMatrix<int,ScalarType> > Belos::GmresIterationState< ScalarType, MV >::z

The current right-hand side of the least squares system RY = Z.
